kbharathsreddy/pgadmin4 repository overview

⁠pgAdmin4 Docker

This is a simple Docker image for running pgAdmin 4 in a container. The default configuration is not intended for production use (it runs in "desktop mode", so authentication is disabled).

This image uses an unprivileged user, and uses port 5050 instead of 80. To access the web-interface on port 80 instead of 5050, you can map the port using -p 80:5050.

Using: pgAdmin 4 v4.8

⁠How to use?

⁠Quick start

To see this image in action, run the following command;

$ docker run --rm -p 5050:5050 kbharathsreddy/pgadmin4

This starts a one-off container in non-detached mode, and container logs are printed in your terminal. After the container has finished starting, visit http://[your-docker-host]:5050 in your browser to try pgAdmin 4.

To exit and remove the container, press CTRL+C in your terminal.

⁠Practical example

This example uses a custom network, and runs a PostgreSQL container.

# create a custom network for easier connecting
$ docker network create pg

# start a postgres container
$ docker run -d -e POSTGRES_PASSWORD=password --network=pg --name postgres 

# start pgAdmin container
$ docker run -d -p 5050:5050 --name pgadmin --network=pg kbharathsreddy/pgadmin4

Now visit http://[your-docker-host]:5050 in your browser. You can add the postgres database (hostname is postgres, password is password) to test if everything is working.

⁠Persistent data

Persistent data is stored in a volume, located at /pgadmin/. This allows you to upgrade the container to a new version without losing configuration.

The following directories can be found inside the volume;

• /pgadmin/config/pgadmin4.db - SQLite configuration database
• /pgadmin/storage/ - other storage

You can override the storage location using the PG_ADMIN_DATA_DIR environment variable

⁠Unprivileged user

pgAdmin runs as an unprivileged user (pgadmin) with uid:gid 1000:50. The uid:gid is selected for compatibility with Docker Toolbox, and allows you to bind-mount a local directory inside the container for persistent storage

For example, to bind-mount the /Users/me/pgadmin directory as storage directory;

$ docker run -d -p 5050:5050 -v /Users/me/pgadmin:/pgadmin kbharathsreddy/pgadmin4

⁠Runtime configuration

This image can be configured at runtime, by setting environment variables;

• PG_ADMIN_DATA_DIR directory to use for storing data (defaults to /pgadmin/)
• PG_ADMIN_PORT port to listen on (defaults to 5050)
• PG_ADMIN_SESSION_DIR directory to use for storing server-side sessions (defaults to /dev/shm/pgAdmin4_session)
• DEBUG enable debug mode (detaults to False)
